They become more stable because they achieve a full outer shell of valence electrons with the magic number of 8.

3.9 g + 12.7 g = 16.6 g
The sum of the masses of potassium and iodine equals the mass of the product, potassium iodide. The results are consistent with he law of conservation of mass.
Hope this heeeelllllllpppppppp
